He is the leader of the Sharks street gang. His appearance is different from other gang members; unlike the others, he has a dragon patch on the back of his shirt and has a purple belt. The Sharks' leader's main weapon is the Ruger assault rifle, which he used in the missions The Chase and Phnom Penh '86.

Phone Call

The leader is possibly the man who phoned to Tommy, after Tommy murdered Leo Teal. He asked Tommy where is (the now-deceased) Leo. Tommy said that Leo has "gone away for a while".

Diaz' Money

"You're on MY turf asshole! You're going down!"

―The Sharks' leader's last words, before being killed in a shootout by Tommy Vercetti

The leader apparently stole 3% of Ricardo Diaz' money, making Diaz very angry about it. Diaz sends Tommy Vercetti, who finds the leader. The leader begins to shoot at Tommy and later escapes with a BF Injection. Tommy follows to see where he hide Diaz' money, at a villa that is controlled by the Sharks.

Later, Diaz sends Tommy and Lance Vance to kill him at his own villa, destroying his gang and taking back the money. During a short shootout between them at the top of the villa, he is killed by Vercetti, who takes back the money to Diaz.

Strangely, even after his death, the Streetwannabe's are not hostile to Tommy.

Vehicles

During "The Chase", the leader's seen with a BF Injection, which was driven by one of his men to the hideout.
